Am I calculating MPG correctly?

My normal fill-up is usually done when the gas gage goes into the normal flashing mode and the Yaris will take about 10gal (38L) to fill.

Of course I always fill it all the way to full

I just filled up so today's equation is:

2623 (Odometer reading now at fill-up)
- 2262 (Reading at last fill-up)

361 divided by 11.551 gallons = 31.252 MPG

Is this right? I am doing mostly city driving so I would like to get this up to at last 36 MPG if I can; I'm in Florida so must run the A/C while driving.

Thanks for any input; my last reading was 32 MPG.

no one seems to have commented on it, but isn't 32mpg lower than expected for this car?? =/

It's just a tad low, but the info is incomplete; I simply cannot believe that he was able to put over 11.5 gallons in the tank -- it's skewed.

The tank may hold 11.1 gallons but the filler tube holds some volume too. 11.55 gallons had to be pretty close to empty. I did 11.5 gallons once.

I'm the original poster; yes I did put 11.55 gallons in; my new question is how can i get my MPG to be better than 32 MPG ? I have to run the A/C as I'm in Florida; I try not to hit the gas too much; dont speed; about 80% city/20% highway driving; thanks for any input guys
